Space

Space at large as the setting — the story ranges across ships, habitats, and worlds, none of them its single home. Stacks with the specific term rather than replacing it: a roaming space opera carries space AND other-star-systems. Alone only when no child term fits. Not implied by merely being off Earth: a book anchored to one alien world takes other-star-systems without this term, one vessel spaceship, one orbital space-station, the empty reaches between stars deep-space.
